DEFLECTING-DAMEER ARRANGELTENT FOR STOVES.

moams.

To all whom it may concern:

Be 1t known that we, RICHARD C. Humans and JOHN C. ZnMLo, both citizens of the United States, and residents of the town of Calamus, in the county of Dodge and State of llisconsin, and of Beaver Dam, in the county of Dodge and State of Wisconsin, respectively, have invented certain new and useful Improvements in Deflecting-Damper Arrangements for Stoves; and we do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to stoves more particularly of a type adapted for burning the more volatile solid fuels such as soft coal and wood, and is directed to the provision of an improved draft means for association therewith.

A common disadvantage encountered in various types of stoves wherein wood or soft coal is burned is that when the normal draft means of the stove is open, a too rapid combustion takes place which is wasteful of the fuel, and when the draft means is closed to promote a slower combustion, the gases given off by the fuel escape from the stove in an objectionable manner. It is, however, desirable under certain conditions'to provide a direct draft for the stove, particularly when starting a fire therein.

It is the primary object of the present invention to provide a means whereby the products of combustion in the stove may be made to travel in a tortuous path to thus reduce the normal draft of the stove in a manner permitting the free outlet of the gases through the chimney, and also to provide an increased heating surface in connection with the gases. the foregoing arrangement being procurable in a manner not interfering with the direct draft through the stove when such draft is desired, as in starting a fire.

It is further an object to provide an improved deflecting means as above described which is exceedingly simple in nature, and which may readily be associated with various conventional types of stoves now in use.

A further and more specific object resides in the provision of an exceedingly simple double damper means operating in connection with the deflecting device for procuring various operations thereof.

With the above and other objects and advantages in view, the invention resides more Specification of Letters Patent.

particularly in the novel combination, arrangement and formation of parts more particularly hereinafter described and particularly pointed out in the appended claim..

In the drawings: Figure 1 is a side elevational view of a conventional type of stove, with the intermediate upper portion thereof broken away in section to show the improved deflecting device, this sectional portion being in a plane indicated by the line 11 of Fig. 2. Fig. 2 is a transverse sectional view through the stove on the line 22 of Fig. 1.

Referring now more particularly to the accompanying drawings, 5 designates the cylindrical body of a conventional type of stove adapted for burning wood or soft coal, and provided with the usual fuel door 6 and with the stove pipe 7 extending from one side of its top. The improved deflectlng device comprises a circular plate 8 dis posed transversely in the upper portion of the stove body above the door 6 to form a partition therein, and this plate is secured in place by bolts 10, passed through the wall of the stove and through upstanding lugs 11 formed at the peripheral edge portion of the plate, the plate being perferably of relatively thin material and strengthened by the radial ribs 12 on its under face.

Directly under the stove pipe 7 the plate is provided with a passage 13 which is formed by cutting away its adjacent edge portion and at a diametrically opposed portion the edge of the plate is again cut away to provide a passage 14:. Associated with these openings for selectively closing them are damper members comprising plates 15 provided each with a transverse rib flange 16 extended past the inner edge of the plate and pivoted between pairs of upstanding ears 17 carried by the body plate 8 immediately inwardly of the respective opening. A link 18 is pivotally connected with the plates by passing its laterally turned ends through apertures in the rib flanges 16 forming eyes and for operating the link, a shaft 19 is passed into the stove transversely of the link and is lournaled in the wall of the stove and in an upstanding lug 20 on,

the body plate 8, the inner end of the shaft terminating in an offset crank portion 21 engaged in an opening 22 in the intermediate portion of the link. Thus upon rotating the shaft, the plates may be operated to close one of the openings 13 and 14 and open the other opening.

It is noted that by the particular arrangement of the laterally turned ends of the link 18 of the crank portion 21 of the shaft 19 that all of the parts are held in assembled relation without the necessity of using cot- V tor-pins or the like.

The present device is adapted 5 for use either in conjunction with the usual damper of the stove pipe 7, or independently thereof. When the passage 13 is opened and the passage 1% closed, the gases of combustion pass directly upwardly through the stove pipe 7 andthus promote rapid combustion of the fuel. When the passage 13 is closed and the passage 1% opened the gases pass through the plate at a point most remote from the chimney and must pass transversely across the stove and through the stove pipe. Thus a tortuous path is obtained for the gases to reduce the draft of the stove and a greater heating is procured by reason of this movement of the gases. This arrangement however, does not interfere with a free passage of the gases from the stove, such as would be occasioned by closing off the draft, which is the usual means employed for reducing the combustion.

The present device is illustrated more particularly as an attachment which may be placed in existing types of stoves, and in incorporating the present arrangement in the manufacture of a stove, various modifi- Ooriies of this patent may be obtained for cations of structure may be resorted to without inany manner departing from the spirit of the invention.

o claim:

A deflecting damper attachment for a stove having a pipe opening in one side of its top portion, said attachment comprising a transverse partition in the upper portion of the stove provided with an opening at a point adjacent the pip opening and with an opening remote from the pipe opening, ears on the partition adjacent the openings, a bearing ear disposed centrally on the partition, closure plates for said openings pivoted to the first named ears, apertured projections on the closure plates, a centrally apertured link having laterally turned ends engaged in said apertured projections and an operating shaft passed through the stove and journaled in the bearing ear with its inner portion laterally offset to provide a crank arm engageable in the aperture of the link.

In testimony that we claim the foregoing we have hereunto set our hands atBeaver Dam, in the county of Dodge, and State of Wisconsin, in the presence of two witnesses.
